Although there has been extensive research on students' understanding of the particulate nature of matter (PNM), there is still a lack of research on contexts that can be used to teach this challenging topic. In a previous design-based research study, the authors developed a teaching-learning sequence (TLS) on the PNM in the context of crystal…

Science education is crucial for fostering knowledge across academic disciplines. Past efforts to enhance science achievement at the elementary level have explored various instructional strategies. Among these, the Understanding by Design (UbD) model has shown notable potential in improving science achievement outcomes compared to traditional…

The primary objective of this research was to investigate the effects of model-based science instruction on the conceptual development of 7th grade students in the topic of electricity. This qualitative research was conducted during the 2022-2023 academic year, using purposive sampling method. The study comprised 33 7th grade students (18 boys and…

Teaching with analogies is an important pedagogy that helps learners construct abstract conceptions through reasoning with something familiar. Heat concepts were chosen for this study because they have an intangible nature and involve complex mechanisms that often challenge school-aged learners. Learning this kind of complex concept with analogies…

Multimodal representations play crucial role in students' learning process that students communicate their ideas by using representations. The main aim of this research is to determine the effects of multimodal representations on students' science learning. Quasi-experimental with pre-test and post-test design was used in this study. This study…

Students' socioeconomic status (SES), school climate, and students' attitudes stand out as important factors that determine academic achievement. The current study investigated the relationship among SES, attitude toward science, school climate, and academic achievement comparatively in terms of countries. Trends in International Mathematics and…

In this quasi-experimental research, the effect of the inquiry-based 5E instruction on students' learning of the topic of the main subatomic particles forming the atom as well as on their level of motivation was examined. The sample for the study comprised 45 ninth grade students enrolled in two randomly selected classes at a public high school…

This study compares the successes of numbers 94 7th grade students in science education with assessment-evaluation questions based on skill and acquisition. Assessment-evaluation achievement tests based on skill and acquisition were developed by researchers towards the measurement of force and acquisitions in friction units taking place in the…

Brain-Based Learning (BBL) is an educational theoretical framework based on principles that derive from important findings about the structure and function of the brain through biology, psychology, and neuroscientific research, and forms a holistic context for a comprehensive instructional approach design. In the present study, a teaching…

Michael Simonson's equivalency theory provided support for this study. Simonson's equivalency theory is built around the idea that while there should be different learning experiences for online and seated students, those learning experiences should be equivalent. Equivalency theory includes equivalency, learning experiences, appropriate…

This study aimed to explore different scientific creativity tests' prediction of students' science performance and domain-general creativity abilities. Two scientific creativity tests were chosen: the "Scientific Creativity Test" and the "Creative Scientific Ability Test (C-SAT)". The Science Performance Test (SPT) and…

Given the growing trend toward using technology to assess student learning, this investigation examined test mode comparability of student achievement scores obtained from paper-pencil and computerized assessments of statewide End-of-Course and End-of-Grade examinations in the subject areas of high school biology and eighth-grade English Language…

This study has two aims. The first is to determine the effect of argumentation and epistemologically enriched argumentation on academic achievement. The second is to determine students' opinions about the effect of the integration of argumentation and epistemologically enriched argumentation into the teaching process on academic achievement. In…

Since 1995, the International Association for the Evaluation of Educational Achievement (IEA) implemented the Trends in International Mathematics and Science Study (TIMSS) as an international comparative study. This article aims at identifying the correlations of science classroom instructions with TIMSS science achievement of eighth graders among…

The purpose of this technical appendix is to share detailed results and more fully describe the sample and methods used to produce the research brief, "COVID's Impact on Science Achievement: Trends from 2019 through 2024. We investigated three main research questions in this brief: 1) How did science achievement in 2021 and 2024 compare to…
